Boltz Lab is designed around real chemistry and biology workflows, so teams can start from a target and a hypothesis and quickly generate, evaluate, and rank candidate molecules. We provide the compute, the scalable infrastructure, and the collaboration layer, so scientists can iterate faster and stay focused.\nYou can read more about our mission, research and product vision on our manifesto.\nAbout the role\nAs an ML Research Engineer/Scientist, you will develop the next generation of machine learning models and algorithms that power Boltz Lab and expand what scientists can do with AI in molecular modeling and design.\nYou’ll collaborate closely with an interdisciplinary team of ML researchers, domain experts in chemistry and biology, and software engineers. Together, you’ll design new model architectures, training objectives, and the high-quality datasets required to train them, pushing performance on fundamental tasks in drug discovery. You’ll also help define how we evaluate progress, building rigorous benchmarks and validation pipelines that connect offline metrics to real-world outcomes.\nThis role is for someone who is a mission-driven technical leader who wants to push the frontier and then turn that progress into capabilities that thousands of scientists can use. You’ll set direction as well as execute while holding a high bar on scientific rigor, strong engineering practices and real-world impact.\nAbout you\nEssentials:\nExtensive publication record in top-tier ML or life-science conferences and journals (NeurIPS, ICLR, ICML, Nature Methods, and related).\nDemonstrated strength in deep learning research and development, including designing new architectures, running rigorous experiments, and performing careful analysis.\nStrong hands-on experience with PyTorch and the scientific Python ecosystem (NumPy, SciPy, Pandas, etc.).\nExperience contributing to and maintaining deep-learning codebases, with a high bar for engineering quality, reproducibility, and testing.\nNice to have:\nExperience training, scaling, and evaluating large models on applied, real-world problems, including building reliable evaluation suites and diagnosing failure modes.\nExperience working in an interdisciplinary scientific environment, especially across ML, biology, chemistry, and physics.\nFamiliarity with the tools, data formats and workflows commonly used in computational biology and chemistry.\nWhat we offer\nOpportunity to drive outsized real-world impact by building tools that empower thousands of scientists across the industry.\nWork alongside one of the most talent-dense teams in the field.\nSignificant ownership and independence, with responsibility for driving projects from concept to deployment.\nHighly competitive salary with substantial equity ownership.","description_format":"text","description_chars":3379,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Drug Discovery","Medical AI"],"lifecycle":[{"event":"open","at":"2026-09-26T21:01:22Z"}],"liveness":{"score":2,"band":"cold","label":"Long shot","p_open":1,"p_active":0.089,"p_room":0.28,"age_days":268,"expected_fill_days":21,"reasons":["conf:46","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-02T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/boltz-ml-research-engineerscientist","json_url":"https://alion.io/job/boltz-ml-research-engineerscientist.json","meta":{"generated_at":"2026-10-03T02:02:33Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":2151,"day_limit":5000,"remaining_today":2849,"minute_limit":60,"resets_at":"2026-10-04T00:00:00Z"}}}
